    Senior .NET Developer

    Romania - Last active: 6 days ago - Tests: 6 - Portfolio: 4

    I am a senior .NET programmer with over 20 years of professional experience, mainly in back-end C# applications using SQL databases - web services and Windows services. I am very familiar with SQL data modeling and normalization up to third normal form. One of my recent accomplishments was changing an error-prone, manual process that was taking three days each month into an automated, five-minute scheduled task using MS SQL Data Tools. Unit testing and test-driven design are very important to me - I wrote a book, TDD by Example, available on Amazon. I don't mind working on pre-existing code without tests but I generally insist on adding them to any code I change.
